primrose You refer to "trivial" issues but the triviality emanates from those with whom you agree. Since you were so keen to tell people you are off to Portcullis House to meet some "real politicians", perhaps you would like to enlighten us as to who they are.
The state of Seamus Milne's marriage is nothing to do with anybody except his wife and family. Had he been prominent in passing judgment on the sexual behaviour of others, then perhaps it would be natural that he be criticised but, as far as I'm aware, he confines himself to political issues. There must on this site alone be hundreds of people who view or post on it, who have had extra-marital affairs or who are in their second or third marriages. Who has the right to pass judgment on them? Nobody, in my opinion.
Is it really being suggested that someone who has an affair should lose his or her job or be ostracised? If that were to be the case, I would imagine a fair percentage of people would find themselves unemployed and shunned by the "righteous".
I think there is a world of difference between swearing about something or someone and swearing at someone. But it seems because Jess Phillips is vehemently anti-Corbyn, it was seen as rather amusing for her to tell a left winger to "fuck off". I also think that, whilst continual swearing can be off-putting, there are far worse things that a person can do.
I know people of very modest means and education who I would consider are decent and respectful of others - what might be described as "well mannered". In fact I have a fairly ordinary background myself and would like to think I am generally quite good mannered. It has nothing whatsoever to do with class, employment status, money - or lineage (as Rigby's post re the Viscount so clearly demonstrates). In the grand scheme of things, however, charm and impeccable manners can be fairly superficial social devices and do not necessarily indicate a genuine care and respect for other human beings.
